Abstract

An embodiment integrated circuit (IC) clock distributor system includes a first IC. The first IC includes a clock synchronizer circuit and a clock generator circuit. The clock synchronizer circuit includes a first input coupled to a first clock transfer path including a replica delay of a portion of a first signal path included in an external IC. The clock synchronizer circuit also includes a second input coupled to a second clock transfer path. The clock generator circuit also includes an input coupled to an output of at least one of a reference oscillator and the clock synchronizer circuit. Delay of the second clock transfer path includes delay of the first signal path.
